At the same time, the base 3 is connected to multiple grounding points, and the current can be separated and guided when struck by lightning.

[0023] like Figure 1 and Figure 3 As shown, the efficient lightning induction mechanism 4 includes a plurality of auxiliary needles 401 fixedly connected to the upper end of the base 3, a connecting ring 403 is fixedly connected to the circumferential surface of the main needle 1, a plurality of connecting rods 402 are fixedly connected to the surface of the connecting ring 403, and the plurality of connecting rods 402 are respectively fixedly connected to the plurality of auxiliary needles 401, and lightning can be separated and guided to the plurality of auxiliary needles 401 through the connecting rods 402. When the main needle 1 and the auxiliary needle 401 are struck by lightning, the circuit is guided to the base 3, and the current is separated and guided.
